O2 sensor ECU

Hey i really need to know where the O2 sensor wire connects to on the ECU. I found a site http://www.**********/faq/articles/95_ecu_pinout.htm

but cant figure out if i should splice it through the Front O2 sensor or the Rear Heated O2 sensor????

What are you trying to splice? A/F gauge?
If your gonna splice a narrow band a/f gauge it would be the rear O2 sensor, after cats.

no problem...just a heads up though dont rely on that for tuning your car. They're way too jumpy and inaccurate at rich readings. Wideband is the way to go but kinda pricey
